How You View This Optical Illusion Might Reveal Your Age

Decades before "the dress" broke the internet, an optical illusion called “My Wife and My Mother-in-Law" had people second-guessing their eyesight. It depicts two images hidden in one illustration: The first shows a young woman turning her face away from the viewer, and the second shows the profile of a much older woman looking to the left. While both perceptions are technically accurate, the way you see the picture may give away your age, according to a study reported by indy100.

The study, published recently in Scientific Reports, looked at 393 subjects of varying ages. Researchers found that the youngest 10 percent of participants were more likely to see the young woman first when shown the illusion, while the oldest 10 percent of participants saw the old woman first.

Research has shown that people spend more time processing the faces of people they consider to be members of their "group" than those outside of it. "The effect of in- and out-groups may be particularly relevant to the processing of faces of different ages," the authors wrote of the study. "A common finding within the field is the own-age bias, where recognition memory is better for faces closer to one’s own age compared to other ages."

“My Wife and My Mother-in-Law" is an example of an ambiguous image or reversible figure—optical illusions that your brain can interpret one of two ways. These pictures are satisfying once you figure them out, but other optical illusions aren't so easy to outsmart.

These Rugged Steel-Toe Boots Look and Feel Like Summer Sneakers

Indestructible Shoes
Indestructible Shoes

Thanks to new, high-tech materials, our favorite shoes are lighter and more comfortable than ever. Unfortunately, one thing most sneakers are not is durable. They can’t protect your feet from the rain, let alone heavy objects. Luckily, as their name implies, Indestructible Shoes has come up with a line of steel-toe boots that look and feel like regular sneakers.

Made to be incredibly strong but still lightweight, every pair of Indestructible Shoes has steel toes, skid-proof grips, and shock-absorption technology. But they don't look clunky or bulky, which makes them suitable whether you're going to work, the gym, or a family gathering.

The Hummer is Indestructible Shoes’s most well-rounded model. It features European steel toes to protect your feet, while the durable "flymesh" material wicks moisture to keep your feet feeling fresh. The insole features 3D arch support and extra padding in the heel cup. And the outsole features additional padding that distributes weight and helps your body withstand strain.

There’s also the Xciter, Indestructible Shoes’s latest design. The company prioritized comfort for this model, with the same steel toes as the Hummer, but with additional extra-large, no-slip outsoles capable of gripping even smooth, slippery surfaces—like, say, a boat deck. The upper is made of breathable moisture-wicking flymesh to help keep your feet dry in the rain or if you're wearing them on the water.

If you want a more breathable shoe for the peak summer months, there's the Ryder. This shoe is designed to be a stylish solution to the problem of sweaty feet, thanks to a breathable mesh that maximizes airflow and minimizes sweat and odor. Meanwhile, extra padding in the midsole will keep your feet protected.

No Squawking, Please: A Backyard Bird Library Is the Star of This Livestream

Many people discovered backyard birding when they were quarantined in their homes at the start of the COVID-19 pandemic. Even if you have a vibrant wildlife population in your area, the Bird Library webcam is worth checking out. As Atlas Obscura reports, the bird feeder at the focus of the livestream resembles a tiny library where feathered guests can misbehave.

Librarian Rebecca Flowers and woodworker Kevin Cwalina were inspired to build the Bird Library in 2015. Located in a backyard in Charlottesville, Virginia, it features a miniature reading chair, bookshelves, and a reception desk. The decorations are even updated to match the seasons; the feeder currently sports a banner that says "Summer Reading." The main differences setting it apart from a real library are the bird seed scattered on the floor and the avian visitors.

The Bird Library attracts a diverse collection of patrons. Sparrows, cardinals, and mourning doves have been recorded perching on the librarian's desk and checking out the reading materials. The occasional squirrel has also been known to stop by.

Live video of the feeder streams on the Bird Library's YouTube page and website 24 hours a day, 7 days a week. You can play the video below to check in on the current guests. If the backyard Bird Library has inspired you to find birds closer to home, here's some gear for beginner naturalists.
